Description
The CDB4340/41 evaluation board is an excellent
means for quickly evaluating the CS4340/41 family of
24-bit, stereo D/A converters. Evaluation requires an an-
alog signal analyzer, a digital signal source, a PC for
controlling the CS4341 and a power supply. Analog out-
puts are provided via RCA phono jacks for both
channels.
The CS8414 digital audio receiver I.C. provides the sys-
tem timing necessary to operate the Digital-to-Analog
converters and will accept AES/EBU, S/PDIF, and EIAJ-
340 compatible audio data. The evaluation board may
also be configured to accept external timing signals for
operation
development.

... CDB4340/41 SYSTEM OVERVIEW The CDB4340/41 evaluation board is an excellent means of quickly evaluating the CS4340/41. The CS8414 digital audio interface receiver provides an easy interface to digital audio signal sources in- cluding the majority of digital audio test equip- ment. The evaluation board also allows the user to supply clocks and data through a 10-pin header for system development ...

... The CS4340/41 requires careful attention to power supply and grounding arrangements to optimize performance. Figure 10 details the power distribu- tion used on this board. The CDB4340/41 ground plane is split to control the digital return currents in order to minimize digital interference. The decou- pling capacitors are located as close to the CS4340/41 as possible ...
